This application 'is a division o applica tion Serial No. 498,979, tiledby me in the United States Patent Oliice May 28, 1909. Referring moreparticularly to the drawings and 1n the present exemplilication of theinvention, the numeral 15 designates generally a casing which may beconstructed of any desired material and may lbe of any desired size andconfiguration. In the preeent cxempliication of thisJ invention, how-`ever, the casing is preferably rectangular in oonfiguiatiomoomprisingfront, back and sido walls. The casing is provided with an i inner walland each of the sections of this wall is constructed of a .body `portion1f` shown more clearly in Fig. 2 to which is secured strips 17. The bodyportion 16 of the `back and side Wallsoff the refrigerator propo:` is ofa size to eistend throughout the entire height of the Ycasing and eachof `the walls is constructed as a single unit.

Alfter fthe strips 17 have been secuned to one face of the bod portion,a suitable heat insulating material7 18 is placed upon the body portionbetween the strips 17, and the space between the strips and above tbeheat insulating material 18 is filled with suitable beat non-conductingmaterial 19, such as mineral wool, asbestos and the like, and the spacesare filled substantially flush 'with the exposed faces of 'the strips. Asheet of asbestos or other suitable heat mon-conducting materialQO isthen placed across the strips and the packing and :secured in anydesired or suitable manner. The top and bottom of the compartment isconstructed :in the same manner. After the walls and bottom have beenthus cfimstructed, the bot-- tom is first pla/ced within the outereasing so as to rest upon the bottom thereof Wirth Y the insulatingmaterial 20 in engagement with the bottom off the Iouter casing,,anteiwhich the sides and back wall of olie comartment are placed inposition `and ad- )usted against the walls off the outer casing vlength. The

66 /to the edge uponwhich theA flange 24 isar- E with the insulatingmaterial 20 in engagement therewith. rlthese walls may then be securedin position in any desired or suitable manner not necessary toillustrate but in a manner to permit the walls to be readily removedwhen desired, and at the same time hold them in position when adjusted.The top of the inner casing may then be placed in position so as to besupported by the sides and back walls.

rlhe casing is divided by an upright partition into two compartments toform an ice bunker `designated generally by the reference numeral 21,and a food compartment designated generally by the reference numeral 22in Fig. 2. The partition between the ice bunker and the food compartmentis of a knock-down construction and is preferably constructed of metalcomprising two or more uprights 23,the body portions of which arepreferably of channel formation, as shown more clearly in Figs. 3 and 6,and projecting laterally beyond the free edge of one of the sides ofthechannel is a flange 24 whichis provided with a series of keyholeslots 25 at intervals throughout its flange 24 is arranged adjacent ofthe channel and is adapted to rest against one of the inner walls o thecompartment. One of these uprights is referably arranged adjacent therear an one adjacent the front wall ofthe compartment; `Thesupportadjacent the front wall of the refrigerator compartment isprelerably arranged adjacentthc stile 26 (see Fig. l) between the doors27, 28 and 29, which open through the front wall of the refrigerator andthrough which access may be had rethe open edge spectively Vto the foodcompartment, the -ice bunker Aand the portion of the food compartmentbelow the ice bunker.l The walls to which these uprights are secured arerovided with pins or projecting'lugs 30 w ich are provided with heads,of a size topass through the openings 25 so that the uprights mabelowered to cause the shanlrs of the pins or projections to enter thesmaller portions of the slots to support and secure the uprights inposition so` that the body portion of the'uprig'htwill be held spacedfrom the wall' by means of the sides of the channel. These uprights areprovided with slots-31 which pass through one edge thereof, preferablythe edge opposite downwardly.

ranged, and incline provided 'number of these slots 31 may be throughout,the length of the uprights 23.

'A series of members or partitions 32 are provided and each ispreferably constructed of a vstrip of sheet material of'a thicknesssubstantially equal to the width of the slots 31 and of a heightsubstantially equal to the length of the slots.

One edge of the members 32 is deflected to form a' depending flange 33along one edge. The other edge of the members 32 is rolled as at 34 toform a reinforce for the edge and this rolled portion terminates shortof the extremities of the members 32 as at 35 a distance equal to thewidth of the sides of the body portion 23 of the upright. Theextremities of these members or partitions 32 are inserted in therespective slots 31 in the uprights 23 with the rolled portions 34preferably located adjacent the lower extremities of the slots and withthe deflected portions 33 adjacent the outer edges of the slots. Whenthese members or sections 32 are arranged in position and supported bythe uprights,` they will form ports or passages which extend downwardlyfrom the ice bunker 21 into the food compartment 22. By constructing thepartition in this manner it will be apparent that the partition may beknocked down or separated for the purpose of cleaning the same. ln orderto prevent accidental displacement of these members or partitions 32during transportation, a suitable lock may be provided. A simple andefficient means for accomplishing this purpose comprises a member 36(see Figs. 2 and 9) which is preferably constructed of a strip of metalhaving a curved or bent end 37, which is adapted to engage over the topedge of one of the sides 38 of the upright 23. This y member 36 is ofany suitable length but is of a length substantially equal to the lengthof the side 38 of the upright so that the body plortion of the member 36will extend over t e edge of the partitions or members 32 .adjacent theopen portions of the slots 31. The member 36 may be provided with a`slot 40 adapted to receive a fastening device 41, such as a turn buttonor the like, which is supported by the side 38 of the upright and whenthis member 36 is thus locked in position, it will be apparent that thepartitions or members 32 will be held against displacement. One of thesemembers 36 ispreferably provided foreach of the uprights 23. Byconstructing the upparent that the extremities of the members bor4partitions 32 will enter the slots 31 .a

suicient distance to project `beyond the sides thereof to form anadequate support for the members or partitions. The other side 42 of theuprights is cut out portions 43 are deflected to form laterally`projecting portions extending beyond the side. 4Secured to the oppositeWall of the food. compartment and adjacent the corners thereof, areuprights 44 which are also provided' with cut out portions deiected asat 45 to form lateral projections cop er ating with the projections 43,land ythese coperating projections 43, 45, .form

supports for the shelves 46 in the food com-l partment. The members44are also proi right 23 of channel formation, it will be apcut out andthe vided with lreyhole slots 47 adapted to oooperate with suitable pinsor projections 48 on the wall of the compartment in a manner similar tothat in which the slots in the uprights 23 cooperate with the pins orprojections for removably and securely holding them in osition.

Arranged elow the partition formed by the uprights 23 and the members 32is a partition 49 (see Figs 2 and 5). This partition is preferablyconstructed of sheet material and the opposite edges 50 thereof aredeflected to form lateral projecting portions and each of-thesedeflected portions 50 is provided with bayonet slots 51 opening throughthe edges thereof, which coperate with pins or projections 52 onopposite walls ofthe compartment. This partition 49 is of a length toextend across the refrigerator compartment so that the deflectedportions 50 thereof will rest against the opposite 'walls and whensecured in position by the bayonet slots 51 and pins or projections 52the artition 49 will substantially form a continuation or dependingportion of the partition formed by the uprights 23 and the members 32.This section 49 of the par-v tition preferably terminates some distanceabove the bottom of the compartment to form an air circulation passage53 and the bodyportion of the partition is cut-out and the cut-outportions are deflected as at 54 to form shelf supports similar to thesup- I ports 43, 45. A support 55, similar to the support 44 is provi edwith laterally deflected portions 56 and is secured to the wall of therefrigerator compartment on the opposite side of the partition 49 sothat shelves 57 may be supported on each side of the partition 49, theshelves 57 on one side of the partition extending below the ice bunker21.

Supported in any desired or suitable manner, preferably by means ofangle irons 58 adjacent the base of the uprights 23 is a pan 59, shownmore clearly in Figs. 2 and 7, which is provided with elongatedapertures (30 in its bottom. This pan serves to form the bottom of theice bunker 2l and an ice supporting rack 61 having end members 62 issupported in any desired or suitable manner, either by means of the endsof the members 62 nesting upon the edges of the pan 59 or by means ofsuitable anglo irons 63 provided for the purpose. The extremities of theend members G2 project for some distance beyond the sides of the body 61to form air circulation openings 64. The bottom of the pan preferablyinclines down- Wardly and toward the rear, as shown more clearly in Fig.,4, and arranged around the apertures 60 are Iianges 65. The panreceivesthe drip water from the ice G6 and the flanges 65 prevent thewater fromvpassing through the apertures 60. The pan is 65 provided witha discharge outlet opening 67 at the rear thereof, around which open ingis arranged a flange 68 adapted to telescope into the upper extremity ofun over How pipe 69, which is supported in any desired or suitablemanner. The lower extremity 7() of the overflow pipe telescopes with theupper extremity 71, of a pipe 7 2 which leads to the sewer or any otherpoint of discharge.

lilith' this improved construction of refrigerator compartment, the aircurrents will pass from the ice bunker downwardly into the portions ofthe food com artmexit below the ice bunker to be discharged through theopening 58 to the other side of thepartition 49 and will rise in theportion of the .food compartment on'the other side of the partitiontoward the top of the compartment. During this rising movement, the aircurrents will pass into the ports or passages formed by the members orpartitions 32 vand will be drawn therethrough into the ice bunkerwherethey will contact with the ice, causing the ltemperature of the aircurrents to be lowered. As the temperature is lowered the air willcontinue to circulate from the ice bunker and through the foodcompartments.

The door 27 in the outer casing 15 is ar-v ranged so as to close thefood compartment on one side of the ice bunker and the artition 49,through which access .may be ad to that portion of the food compartment.The door 29 is arranged to close the portion of the food compartmentbelow the ice bunker and the door 28 is arranged to close the opening inthe casing through which access may e had to the ice bunker so that icemaybe supplied to the ice bunker without opening the closures 27 and 29.

lVith this improved construction of refrigerator it will be apparentthat the entire inside of the refrigerator may be removed including theinner walls and partitions and the partitions or Inembers 32 which formthe air passages from the food compartment to the ice bunker may beremoved and thoroughly cleaned and after being cleaned may as readily bereplaced.

Obviously the shelves 4G and 57 may be provided with apertures oropenings 73 therethrough so as not to im ede the circulation of airthrough the foo compartment..
